Grease Trap Regulations in Nebraska

Overview

Nebraska food businesses must follow FOG pretreatment rules. The Nebraska Department of Water, Energy, and Environment (DWEE) oversees these rules. DWEE was formed in 2025 by merging the Nebraska Department of Natural Resources and the Nebraska Department of Environment and Energy.

Local sewer utilities in big cities run active FOG programs. They require grease trap install, regular pumping, and good records. Most enforcement is at the city level. Cities like Omaha and Lincoln run their own pretreatment ordinances under state and federal Clean Water Act rules.

Governing Authorities

DWEE works to protect Nebraska's air, land, and water. At the state level, DWEE oversees wastewater discharge and pretreatment standards. But day-to-day FOG enforcement goes to cities and local utilities.

Major city enforcers include:

• Omaha Public Works: Runs FOG pretreatment rules for all food businesses on the city sewer system.
• Lincoln Transportation and Utilities: Runs a full FOG control program with set trap sizing and pumping rules.
• Grand Island Public Works: Runs a Preferred Hauler Program. The program sets standard cleaning, records, hauling, and disposal of commercial grease waste.

All food businesses in Omaha must keep service records for at least 3 years. That standard matches best practices statewide.

Key Requirements

Interceptor Installation and Sizing

Food businesses that prep, cook, or serve food creating FOG must install grease traps sized to their use. Full-service restaurants with fryers, grills, and big ranges usually need outdoor gravity traps. Smaller spots may use indoor traps.

Cleaning Frequency

Nebraska cities follow the standard 25% rule. Traps must be cleaned before grease and solids hit 25% of trap depth. Common pumping schedules:

• Most Omaha businesses pump every 1 to 3 months. Busy kitchens pump monthly.
• Indoor traps often need service every 30 to 60 days due to smaller size.
• Outdoor gravity traps usually need pumping every 60 to 90 days based on volume.
• Sites with heavy FOG output may face more inspections and tighter cleaning rules.

Manifest and Record-Keeping

All food businesses must keep full waste records, including:

• Licensed hauler manifests with date, volume pumped, and disposal site.
• Records kept for at least three years.
• Proof of service from licensed haulers.
• Self-monitoring logs to show you meet the 25% rule.

Omaha bans dumping grease right into the sewer. Breaking this rule can bring enforcement action and fines.

Fines and Enforcement

Nebraska state law does not set one fine for all FOG violations. Cities enforce their own rules with penalties that vary by area. Enforcement tools include:

• Routine Inspections: City utilities run scheduled and complaint-based checks of grease traps.
• Violation Notices: Sites out of compliance get notices with fix-by deadlines.
• Financial Penalties: Businesses may face fines from the city for skipping trap upkeep. Penalties grow for repeat issues.
• Health Code Violations: Skipping trap upkeep can lead to health code violations from local health departments.
• Cost Recovery: Fines of $100 or $200, civil penalties, compliance plans, install of properly sized outdoor traps, and cleanup costs for blockages and sewer overflows may apply.

Enforcement may also require new trap install or upgrade, more inspections, and in bad cases, an order to stop operations until fixed. Businesses pay all costs for sewer blockages traced back to their site.

Major City FOG Programs

Omaha

Omaha Public Works runs a strong FOG program for all food businesses on the city sewer system. The city requires all food businesses to have properly sized grease traps. Trap size is set by food prep type and volume. The city sets pumping schedules, usually every 1 to 3 months based on trap size and use. Businesses must keep service records for at least 3 years. The city bans dumping grease right into the sewer. Violations can bring fines, more inspections, and orders to upgrade or replace bad equipment.

Lincoln

Lincoln Transportation and Utilities runs a full FOG control program. It requires trap install, set pumping, and licensed hauler manifests kept for three years. The city uses the 25% rule and runs routine compliance checks of food businesses. Busy restaurants and big institutional kitchens must install outdoor gravity traps. Smaller sites may use proper indoor traps. Lincoln stresses best practices like staff training, proper waste disposal, and a ban on garbage disposals tied into grease traps.

Grand Island

Grand Island runs a Preferred Hauler Program. It ties hauler companies to the city for set cleaning, records, hauling, and disposal of grease waste. The goal is to keep grease out of city sewers. The city requires all food businesses, including food trucks, to follow best practices and keep traps in good shape. Grand Island teaches restaurant owners about FOG risks. The city has tracked major grease build-up in local sewer lines, which shows why compliance matters.

Bellevue

Bellevue's sewer system is part of the Papillion Creek basin. Food businesses inside city limits must follow local and regional FOG rules. Sites should install and maintain proper grease devices for their use. They should follow the 25% rule for pumping and keep records for inspections. Bellevue works with regional utilities to keep FOG standards in line.

Frequently Asked Questions

How often must I pump my grease trap in Nebraska?

Pumping timing depends on trap size, business type, and local rules. Most Nebraska cities require pumping before grease and solids hit 25% of trap depth. That usually means every 1 to 3 months for outdoor traps and every 30 to 60 days for smaller indoor traps. Busy spots with heavy fryer use may need monthly service. Your local utility can give exact rules based on your business.

What records must I keep to prove compliance?

Nebraska food businesses must keep waste hauler manifests showing the date of each pump-out, volume removed, hauler name, and disposal site. Keep records for at least three years. Show them when an inspector asks. Sites should also log routine FOG checks to prove they meet the 25% rule. Missing records can cause a violation even if your trap is clean.

Can I use additives or enzymes instead of pumping my grease trap?

No. Chemical additives and enzymes are not a substitute for proper trap upkeep. Many local rules ban them. These products may break up grease in the trap. But they just push the problem downstream into the city sewer, where the grease hardens and causes blockages. Nebraska cities require physical removal of grease and solids by licensed haulers. Using additives instead of scheduled pump-outs will lead to violations and possible enforcement.
